What is a virus?
A virus is computer code which inserts itself into another program. When the program runs - the virus code is also executed.** Please Note: Viruses are NOT ONLY spread through e-mail. **
A machine can become infected through a variety of methods. One of these is to download a file from a compromised web server. Any time a file is downloaded (from an FTP server, from a friend's floppy disk, purchased software, etc.), you run the risk of infecting your machine.
